Apple ios and 802.1x authentication issues

Happy holiday weekend to all!

Question about the latest apple iOS update - we are seeing strange behavior from our employee iphones with regard to 802.1x. Once updated to the latest iOS version, the users are kicked off the wireless network and are prompted to log back in only with their passwords, usernames aren't required. It also appears that they are forced to reauthenticate a number of times during the day. IPads with the latest version are not experiencing this issue. Has anyone else run into this at all? I've searched the apple site for known 802.1x bugs for the new iOS version and haven't been able to come up with much.
